Pusan has experienced some different paths of urbanization and industrialization compared to other cities, and has faced the problem of over-saturation in environmental capacity. Pusan needs to find out sustainable development strategies based on Agenda 21 by UNCED in 1992 to secure urban renewal. Therefore, Pusan`s sustainable development strategies focus on the 1)research on environmental capacity and reasonable population accommodation 2)supply of basic environmental facilities for the human settlement 3)protection and efficient management of environmental pollution 4)saving and control of energy and other resources 5)independent and stable execution of plan based on biological relation 6)harmony between nature and urban spatial organization. In addition, these policies can be suggested along with the conclusions; First, establishment of green plan-middle and long term environmental goals included in the urban planning to reduce environmental deterioration and pollution. Second, computation of sustainability index-the index is necessary to sustainable urban development, which is related with green GNP of the national level. Third, capacity estimation of nature and social environment-estimation of environmental capacity to the civilized area is required become an ecopolis, and is required to focus on the western area of Pusan which has high degree of potentiality.

Varing the flow velocity of solution and particle diameter, the mass transfer coefficient of the local electrode on current feeder has been measured in an empty flow reactor, an inert fluidized bed electrode reactor, and an active fluidized bed electrode reactor. It had its maximium value when the bed porosity was 0.6 to 0.65 and decreased with increasing the height of local electrode. The mass transfer coefficient was found to be high especially when bigger particle was fluidized. Electrochemical deposition of copper dissolved in the synthesized wastewater has been performed in the active fluidized bed electrode reactor. The deduction rate was higher than 90% and the residual concentration of copper decreased to less than 5ppm.

우리나라에서 생산되고 있는 60여종의 약용식물의 지방산 조성을 조사하여 식물체의 부위 와 종류에 따른 지방산 조성의 특성을 관찰한 결과 아래와 같은 결과얻었다. 1. 달맞이꽃종자, 컴프리잎, 지치뿌리에서 각각 총지방산함량의 9.1, 3,5, 7,2%의 GLA가 검출되었으며 달맞이 꽃종자가 컴프리잎이나 지치뿌리보다 GLA의 절대량이 많았다. 2. 들깨종자, 참깨종자, 호박종자등의 지방산이 양(量)과 불포화도면에서 좋은 자원임이 확인되었다. 3. 식물체의 잎, 줄기, 뿌리에서의 지방산조성은 종자의 경우에 비하여 18 : 3의 분포 비율이 현저히 높게 나타났으며 18 : 0의 비율은 비교적 같게 나타났다.
